让Nginx和Node.js发挥出色

Question

I have an nginx/node.js server I'm trying to configure. Basically it's just the issue of running 2 web servers on port 80 at the same time. I have www.mysite.com that I need to point to nginx on port 80. But I also have a node.js server that I need api.mysite.com to point to port 8888.

I'm messing around with proxy_pass in my config ( http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass ) but with no luck. I also tried this https://stackoverflow.com/a/20716524/605841 with no luck.

If anyone has any tips that would be great. Thanks in advance.

Nginx public dir: /var/www/html. Express app location: /var/www/html/myNodeAppRoot

Here's my /etc/nginx/sites-available/api.mysite.com file (sym linked into sites-enabled):

server {

    listen 80;

#    server_name ~^(?<login>[a-z]+)\.api\.mysite\.com$;
    server_name api.mysite.com$;

    location / {

#       root    /var/www/html/myNodeAppRoot;

#       proxy_pass http://unix:/tmp/\$login.api.mysite.com.sock:$uri$is_args$args;
        proxy_pass http://unix:/tmp/api.mysite.com.sock:$uri$is_args$args;

        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

And here's my default.conf file:

#
# The default server
#
server {
    listen       80 default_server;
    server_name  www.mysite.com;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    location / {
        root   /var/www/html;
        index  index.php index.html index.htm;
    }

    error_page  404              /404.html;
    location = /404.html {
        root   /var/www/html;
    }

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /var/www/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        root           /var/www/html;
        try_files $uri =404;
    #    fastcgi_pass   127.0.0.1:9000;
        fastcgi_pass   unix:/tmp/php5-fpm.sock;
        fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    location ~ /\.ht {
        deny  all;
    }
}

Thanks for any help!

Answer 1

I run a bunch of Node.js applications on the same server, while nginx serves some static content. Here's my setup:

# the meteor server
server {
  server_name example.com;

  access_log /etc/nginx/logs/example.access;
  error_log /etc/nginx/logs/example.error error;

  location / {
    proxy_pass http://localhost:3030;
    proxy_set_header X-Real-IP  $remote_addr;
  }

}

I just repeat this block and change the port for each new Node.js app. Then I run Node.js with a different --port 3030 parameter.

nginx can be configured to use unix sockets, which look like an item in the file system. Node supports these out of the box . This allows you to avoid any issues with ports behind nginx.

A good tutorial for setting up a Node app with nginx and sockets can be found here .
